It was in rented room, where Hans and Margarete Hagner established a business to manufacture transparent packages:
sicht-pack HANS HAGNER. Already two years later, their business moved to its first small shop floor. By offering innovative transparent packages and showing a flexible customer orientation, the company grew continuously and ranked as one of the leading manufacturers of transparent packages in Germany by the end of the 70s. The enterprise was transformed into a limited company (German GmbH), and has been trading under the name of sicht-pack HAGNER GmbH since then.

As of end of the year own PETP film manufacturing "Constructive environmental consciousness" Film sales also to third parties

What set the cat among the pigeons at the Düsseldorf "Interpack 87" in the PVC packaging industry, has been put in concrete form in the meanwhile: One of the German leaders in the field of PVC transparent packages, sicht-pack Hagner GmbH (D-7295 Dornstetten/Hallwangen) is going to start its own manufacturing of polyester (PETP) films by the end of the year. At present, a new three-storey operational building having an overall surface of appr. 3,800 sqms is erected. Here, a complete extrusion line and an ultra-modern recycling installation will be installed from end of September. Supplier of the extrusion line is the Barmag AG (Leverkusener Str. 65, D-5630 Remscheid-Lennep) belonging to the Enka group. The dryers come from Somos, the recycling blade granulators from Condux.

sicht-pack Hagner (appr. 100 employees, branch in Canada) is the first German midsize processor of rigid PVC films who gets into the PETP film manufacturing with a considerable investment of some millions. Background: On account of the increasing "discussion about PVC " Hagner didn’t see any other possibility already a long time ago than being on the lookout for substitutional films. The hitherto existing suppliers of films – the well-known German manufacturers of rigid PVC films – were requested by Hagner to include PETP in their array of products. But their backing was missing, "since we were clearly told that they had written PVC across their banner ". Hagner, therefore, took the bull by the horns and decided to start his own manufacturing of PETP films. The new "SP films" are, however, not only produced for his own installation consumption, but are also to be supplied to other processors of films. If required, Hagner is going to install his second extrusion line

The marketing of the "SP films" made of PETP films is run under the header "environmentally friendly" ("Constructive environmental consciousness with the same packaging convenience "), indeed without mentioning PVC directly. By doing so, any legal actions are – cleverly – avoided which might be taken by the PVC lobby who didn’t always pull no punches in the past when fighting against comparable marketing cases. Chief executive Hans Hagner is quite relaxed when expecting such steps. In an interview with KUNSTSTOFF INFORMATION during the last week, he also demonstrated strength in other respects: In the near future he is expecting other midsize packaging manufacturers to turn towards PETP and to the corresponding manufacturing of films. Hagner: "PETP is the basic material of the future for our industrial sector. And competition is good for business "
